So I am struggling with the fact that even in 2013 and v 9.3 Quark can't handle large single documents with lots of photos. I have about 230 pages. Every other page contains at least 2 image files. My iMac has 16 Gb of RAM but Quark still crashes when scrolling through this document. Another reason to make the jump to ID. Quark is making it very hard for me to like them. Especially when I google the problem and realize that this is nothing new, and Quark should have fixed it a long time ago.
But for now I can't do this entire project from scratch in ID, and I can't afford to buy a plugin to convert the document on this projects budget. So what is the easiest way to split the document into book chapters? I started deleting pages and just saving the shortened document under chapter names. But I can't add them to a book for some reason. They do not contain any extra layouts.
